Read a cron expression in plain English
Paste a standard 5-field cron expression — minute, hour, day-of-month, month, day-of-week — to see when it runs and validate each field. Lists (1,15,30), ranges (1-5), steps (*/15), and named months and weekdays (JAN–DEC, SUN–SAT) are all supported. This is the read-and-check counterpart to the cron expression generator; it explains and validates but never computes next run times or applies time zones.
